Introduction of turtle seedlings and culture methods in autumn
Because the turtle seedlings from one environment to another new environment has a period of adaptation, its cycle is 1 month to 2 months, then gradually normal, and the tortoise is a temperature-changing animal, after entering autumn, with the gradual decline of the temperature, the tortoise also grows slowly. The advantage of autumn introduction is to seize the opportunity of slow growth of the tortoise and let it adapt to the new environment. After the beginning of spring, when the temperature rises, the tortoise immediately enters the growth state, and there is no need to adapt to the new environment. In general, the seedlings introduced in autumn enter the growth period 1-2 months earlier than those introduced in spring.

Qiqiao improves the efficacy of internal administration of fish medicine
1. Coincidence lies in prevention. Fish that live in the water are concealed and difficult to find. Once dead fish are found, the loss is great, and the treatment of fish disease is more difficult. Therefore, we should actively implement the guiding principle of "no disease first prevention, early treatment of disease, prevention is more important than treatment", and establish the concept of prevention and drug application. two。 Skillful combination of traditional Chinese and western medicine. Traditional Chinese medicine has the advantages of long-term efficacy, few side effects and low cost of prevention and treatment of fish disease, while western medicine has the characteristics of rapid efficacy and high cost. Practice has proved that mixing some western medicine into effective Chinese herbal medicine can not only quickly improve the curative effect, but also reduce the cost.

Lecithin has the effect of removing plaque of blood vessel wall. On the other hand, unsaturated fatty acids can reduce blood lipids, improve blood clotting mechanism and increase high-density lipoprotein, but do not increase the function of triglycerides, thus reducing the formation of cardio-cerebral vascular thrombosis and preventing arteriosclerosis. It is reasonable for patients with hypertension to eat more sea fish. There are many ways to cook marine fish, including boiled, steamed, braised, stewed, fried and so on.

Three precautions should be taken for fish in winter.
In winter, the water temperature is low, there is little light, there are few phytoplankton in fish ponds, the oxygen production capacity is poor, and the physique of fish is relatively weak because of less feeding and activity, which has a great impact on safe overwintering and growth. In order to ensure the safety and growth of fish in winter, the water quality control and management of fish ponds should be prevented in winter. In order to prevent shallow water, some mariculturists think that the shallow water in the pond in winter is similar to fish. in fact, this is a misunderstanding. In winter, the pond water level is shallow, the water temperature changes rapidly and the temperature difference is large, which will cause frost damage to fish, which is extremely disadvantageous to the overwintering and growth of fish. Fish ponds in winter
